Economic information

Comments on the geologic information

  • Geologic Description = The country rocks at this prospect are mafic volcanic rocks and sedimentary rocks of the Tertiary Orca Group (Nelson and others, 1985). The deposit consists of lenses of quartz, chalcopyrite, malachite, and sphalerite in a shear zone in graywacke near the contact of mafic volcanic rock (Cobb, 1979: OFR 79-973).
  • Age = Probably Tertiary based on the age of the host rocks.

General comments

Subject category Comment text
Deposit Model Name = Cyprus massive sulfide (Cox and Singer, 1986; model 24a)
Deposit Other Comments = Nelson and others (1985) interpret the country rocks as accreted ocean crust. Crowe and others (1992; 1993) and Sainsbury (1993) discuss the genesis of the volcanogenic massive sulfide deposits in this area.. Chugach Alaska Corporation, Anchorage, Alaska has control of these lands.
